MILK-GAN-STEAMING AND WATER-HEATING SYSTEM.

Application filed July 10, 1925.

My invention pertains to a milk can steaming and water heatin system,and 1S specially designed for use in creameries in connection withvarious operations calling for the use of steam and hot water. Chiefamong those is the cleansing of cans in. which milk or cream has beendelivered to the creamery, a novel and eiiicient means being provided inthe invention for performin this operation.

Another object of the invention is to provide a supply of water of atemperature suitable for making tests in connection with the receipt oflarge quantities of cream, and another supply of water 01"- a varyingbath temperature.

Another purpose of the invention 13 the provision of a combined steamproducing and water heating system, having a common burner or heatingelement, the steam and hot water produced thereby being used for theabove named purposes.

Another object thereof is to provide a supply of water of moderatelywarm temperature, to be used in common for the several purposeshereinbefore named.

The above named, andother features and advantages of the invention willmore fully app-ear from the following specification, reference being hadto the accompanymg drawings, in which Fig. 1 shows the invention inelevation, with the casing 6 in section.

Fig. 2 is a plan view thereof.

Fig. 3 shows the boiler 8 in vertical medial section.

Fig. 1 is a detailed view of the top plate 27 ot the casing 6.

Fig. 5 is a similar view of the bottom plate 29 thereof.

The reference number 1 indicates a frame, preferably formed of tubing,in the upper part of which is supported a tank 2. Fixed to the upperpart of said frame is a. dishshaped support 8, provided with lugs a, toreceive the rim of an inverted cream-can 5, and hold the same in suchposition. Beneath the tank 2 is a cylindrical shaped casing 6, in thelower part of which is a burner 7, for gas or other combustiblematerial. Immediately above the burner 7 is a boiler 8, from which apipe9 projects upwardly to a point above the support 3, and within the mouthof a can, when one is supported thereon. Said pipe is held in place by acollar 10, fixed thereto, and bearing against Serial No. 42,836.

the support 3, and the lower end of said pipe is connected with theboiler 8 by means of a plug 11, tapped into the upper part of theboiler.

Comn'iunicating with the tank 2 through the bottom thereof is a pipe 12,with which is connected a coil 18, winding about the boiler 8. Projecteddownwardly from the lower part of said coil is a. pipe 14,loopedoutwardly into a pipe 15, from which a pipe 16 enters the boiler8. A supply 01"" water from the tank 2 is thus permitted to enter theboiler. From the upper part of the coil 13 a connection is made througha pipe 17. with the tank 2, aiding a circulation of water in said tankand through the system of pipes connected therewith. This is furtherenhanced by means of a pipe 18 connecting the pipes 12 and 17.

The upper part of the coil 13 terminates in branch pipes 19, connectedwith a small pair of tanks or pans 20 and 21, each of the pipes 19 beingprovided with handvalves 22, as shown with one of said pipes in Fig. 1.

The admission of a. supply of water to the boiler 8 may be controlled bymeans of a valve in the pipe 16, as shown at 23, said valve beingconnected with an operators rod 24, held in braces at the side of theframe 1. The boiler 8 is'provided with a number of vertical flues 26,through which the heat passes from the burner 7, when the same is inoperation. Upon a supply of water being admitted to the boiler, it isconverted instantly into steam, which finds its way upwardly through thepi pc 9, to the interior of the can 5, thoroughly cleansing andsterilizing the same. The can is then removed, and another one placed inposition, whereupon the operation is repeated.

Thetop plate 27 of the casing 6is provided with a central opening 28,forming a space about the pipe 9, and the bottom plate 29 has severalopenings 30, which permit entry of air to the casing, a circulation ofthe air upwardly being provided for by the opening 28, the heated airpassing through the opening 28 striking against the bottom of the tank2, and assisting in heating the water therein. The temperature of thiswater is further raised by reason of the heated water in the coilentering the same through the pipe 17. The water in said tank is therebyalways maintained at a temperature which will enable it to be quicklyconverted into steam, or raised to a still higher temperature for use intests as mentioned.

Connected with the lower part of the boiler 8 is adrain-pipe 31,provided with a shut-ott' cock at its end, and at the lower end of thepipe is a drain-cock 32, by opening which the entire system may bedrained.

By manipulation of the Valves 22 water may be permitted to enter thepans and 21, and attain different temperatures therein.

Assuming the pan 20 to be designed for a hot bath, in practice thetemperature of the water therein would range from to l lt) degrees,while the pan 21, it intended for testpurposes, would contain a supplyof water of from to degrees.

It will be observed that the machine is simple and compact in form, andconvenient for the purposes for which it is intended.

lVha-t I claim, and desire to secure by Letters Patent, is:

A device of the class described, comprising a frame, a heater casing inthe lower part off said frame, and heater therein, a boiler in saidcasing adapted to receive heat from said heater, a discharge pipeleading i'rom said boiler, a water supply tank and pipe system betweensaid tank and boiler, a coil encircling said boiler and communicatingwith said pipe stem at the upper and lower ends oi said coil, and awater chamber in proximity to said tank and coinmunicating with saidcoil.

In testimony whereof I aflix my signature.
